1 Claim. (Cl. 311.12)

:I-his invention `relatesrto support devices forsewing machines. Moreparticularly, the invention has reference toasupport board in thenatureof an insert, removably and ixedly connectable to the top of a;sewing machine table or cabinet, to supporta selected ,makeVY or modelvofsewing machine.

Heretofore, every make or model of sewing machines, differing in Soniewespect from other machines, Vhas re- .quiredla cabinet ortablejtopspecially eut to support Vthe same. Said table top or cabinet has, as aresult, been incapable. of supporting any other machine except thatflorffwhich it has been particularly designed.

This is, as be appreciated, a somewhat undesirable situation. lt isclearly a matter of some expense to form differently shaped table topsaccording to the particular makes and sizesof sewing machine models.Accordingly, it isV the main` object of the present invention ,toprovide an insert or support board fora sewingmachine which vvv,illr.bedesigned to receive a particular machine, and will vf urthrerrbedesigned so as to beiremovably and iixedly Urn'ountable upon `a Vtableor cabinetgtop, nwithsaid table or cabinet top so designedas to receiveanytiof a-substantial number or Yinserts differing from oneanother inrespect tothe type of machine to be supported thereby.

A Vfurther ,object of importance is to so shape the insert Vvas ,tocause the ,outer conguration ofthe same torsubstantiallyrrnatchianinsertfboard-receiving opening formed-,in `the table Or ,Cabinettenwith-thatrrfi9nfthe insert Ihat'sshaped torreceiveihebese. of. thesewinsmahine w' be supperedbeins formdto thel speialhape and dimensionsthat' render the insertcapabgle fof supporting the particular machine.

Still anotherbect is to Providence@ Q11. the ,cabinet 0f ,fable tcpextending adjacent the insert-@wiring Opening -thereof soshaped as tosupport thepinsert in the provided opening, while at `thesametirnepermittingthe fixed connection of the insert to saidmeansghereby to prevent relative movement or vibration betweenbthe tabletop and insert.

Still another object is to so Adesign the above mentioned means as notto interfere in any way with l the passage of a drive belt from thesewing-machine through the table top and insert to a drivemotorrmountable upon the underside ofthe table top.

AFor further comprehension of the inventiomandvofithe vobjects andadvantages thereof, reference will'beA had to the followingdescriptionand accompanyingidrawings, and tothe appended claim in whieh'the variousnovel' features offtheinvention are more particularly set forth.

jln the accompanying drawings forming a material part ofqthisdisclosure:

Fig. l is aside elevational View of asewingrinnachine table havingmounted therein theinsertqfornied arcprding to the present invention,theV dotted-lines show inga vsewing machine, its associated',drivernotor, and related Vparts.

V"lf'ig. 2 is a fragmentary top1 plan view ofqthetable-,gnd

Althougha table is zilus- .trated, o'm/iouslythe`structure-can beof closed, cabinetlike construction if desired.

n anytevent, Ja drive motor 16 is mounted against lthe underside of thetable top (Fig. l) in the u suaL manner, land by means of a beltvlpassing Vfrom the moton to a .locationabove thertable top, drivesv asewing machine havinga housing tland head 22,

Ordinarily, .the sewing` machine is mounted directlylin anopeningprovidedV in the table top, Vwhich openingis shaped Vto Vreceive Vaparticular machine, and -is not adapted Vto receive anyY other machinediffering from the intended machine inrespect fto location of itsdrivebelt, Athe size Vof its base, and the outer configuration of-saidhase. Hou/ever, in accordance with the present invention, in theillustrated sewing4 machine table there is formeda large, rectangularVopeningfl, 4opening -upon the front edge AVof thetable top as shown toparticular advantage in'Figs. 2 and 6. flhe opening 24 is substantiallyvgreater than the usual opening formed ina sewing machine table top toreceive the machine housing and head.

The insert plate structure member constituting the present ,inventionhas been illustrated per se-inFig. 45, and in the form or'l Figs. L5,vcon'iprises a rectangular, lflat board or plate structure member 26,thetbickness of whichpis equal tothe thickness of the table,top. 14, andthe outerconguration of which corresponds rtoghe shape of opening 24. yAs will be ,notedy in P ig. 2, in length and width theV support plateorboardlmois slightly smaller than the corresponding Ydimensions ofthefopeningj24, by perhapsy Ms of an inch. YThis facilitates Atheseating of the support board 2,5 in the opening V24, without diicultyand without projection of the vfron'tvled'ge of the support boardVforwardly beyond the ,front edgeof the table top.

Formed in the support plate or board 2e is a series Aof openings locatedat the corners thereof, said openings including a pair of back or insidecorner openings 2S, and a pair of outside corner or front openings 34B.

Extending longitudinally of opening 2e, at t eA open front thereof, is arigid, relatively narrow, straightl front support bar 32. Bar V32 is`greater in length than opening 2l,'the ends of thebar underlying thetable top vlhbeyond the ends of opening 2%, asbest `shown in Figs. l and2. The support-bar 32,*aty locations spaced inwardly from the'endsthereof, hasl apertures Sai-that register with the openings 3G (seeFig.l)-whe n the-plate-Q is lfitted into .opening-24.' vThe bar 32,191locations beyond the'ends of opening-24,1has Vother openingsoraperturesl 36.

Bolts 38 extend through the registering .openings), 3,4, toconnect thefront edgefportion or" the platezlto the bar,zZ, whenvtheplate 2,6 visVdisposed in opening 2.4.vsith its front edgepertienssurnertedncn.thebara wing nuts sir-.equivale h .Connecting bolts1.40 areext Ain s 36 en dt elevation with Yafrxslspssi connect the bar32 to the table top in the position previously described herein.

At the back corners of the openings 24, there are provided back supportbars'or brackets 42. These are also formed from strong, relativelynarrow, metal bar or strap material, but as shown in Fig. 2, these aresubstantially Shorter in length than the front support bar 32, withVeach of the rear corner support bars extending diagonal- Y midlengthportion of each corner support bar 42, which i is exposed in the cornerof the Vopening 24, has an aperture receiving a bolt 46. The bolts 46extend through the rear corner openings 2S of the plate 25, saidopenings 28 being in registration with the midlength open-Y ings of therear corner support bars 42.

The corner bars 42 support the rear corners of the plate 26, as will beapparent, and through the medium of the bolts 46, which are fitted withwing nuts, the plate 26 is securely lixed at its rear corners to thetable top.

It will be seen that in this way, the plate 26, though readily removablefor use of any of a selected number of said plates diifering from oneanother with respect to the type of machine which they can support, isswiftly and easily attachable to or detachable from the table top, andwhen attached to the table top, will be held securely against vibrationsrelative to said top.

Means is provided in the plate 26 to facilitate extension of the drivebelt to the supported sewing machine, and care is taken that said meansdoes not interfere with movement or proper positioning of the drive belt18. As shown in Fig. 2 and also in Fig. 4, a short support bracket 48 isspaced longitudinally of the rear edge of the opening 24 from one of thecorner support bars 42. Bracket ing receiving a connecting bolt 50 whichextends through the table top. The other or free end of the bracket 48projects inwardly of the opening, to underlie the board i or plate 26and aid in providing a support therefor.

The bracket 48 and the adjacent corner support bar,

42 are disposed in close proximity to and at opposite sides of atransverse slot 52 formed in the plate 26. Slot 52 extends adjacent oneend of the plate 26, from the midwidth area of said plate 26 to the backedge thereof,

' 48, at one end, underlies the tabletop, and has an openand is inregistration, at sai-d back edge, with a transverse slot 54 formed inthe table top 14. The slots 52, 54 cooperate when the plate 26 isproperly supported to define an elongated opening through which thedrive belt 18 extends. Proper support at this particular location isprovided by the bracket 48 and the corner support bar 42 adjacentthereto.

Assuming that it is desired to mount a particular sewthe usual fiat base60, and said base is of la shape and dimensions corresponding to thoseof the opening 56. Base 60 is thus seated snugly in opening 56, with thecorner portions of the base effectively supported upon the cushionedledges 5S.

When the sewing machine is so supported, the drive' belt 18 can beextended through the registering slots 52, 54, and the structure isready for use.

In Figs. 6 and 7, there is illustrated a different insert platestructure member 26a constructed to supporta different type of.sewingmachine designated atr20a. Y'This illustration is for therpurpose ofshowing how different `inserts, supporting various types or sizes ofmachines,

4 can all be interchangeable in respectV to a single sewing machinetable top such as that shown at 14 having the rectangular opening 24.

ln the modified form, the insert plate 26a has an outer configurationmatching that of the insert 26. As a result, the insert plate 26arcan besupported upon the front support bar 32 and the rear corner support bars42 as well as on bracket 48. In the modied form, however, the opening56a is substantially different in respect to its 'dimensions `and shapefrom opening 56, since a different type of sewing machine 20a, having abaise 60 corresponding to opening 56ais to be supported. Opening 56a,in'this instance, is not provided with cornerY support ledges 53, butrather, has longitudinally extending front and rear ledges 58a (Fig. 7),merging into end ledges 59a, adapted to support the ends of the sewingmachine. j

The ledges 58a, 59a are quite narrow as comparedto the area of thecorner support ledges 58, and this is for the purpose of providingclearance for a sernicylindrical, depending portion 2 of the sewingmachine housing 20a. The portion 62 has ears 64, capable of being boltedto the inner, vertical surfaces of the front and rear ledges 58a,

The belt-receiving slot of the insert plate 26a has been designated at52a, and as in the first form of the invention, is aligned with the slot54 of the table top 14.

Further, in the modified form, the corner openings 36a `are used, and asin the first form, register with the openings 34 of the bar 32, toreceive theV connecting bolts 38. v

The rear corner openings of the modified adapter 26 will be disposedsimilarly to the rear corner openings 28 of t'he rst form of theinvention, to permit extension of the bolts 46 therethrough.

it'will be seen from the above that a single table top 14 can bemanufactured, adapted to receive all the different sewing machines ofthe particular manufacturer. Further, it will be noted that the tabletop 14 can even be adapted to receive the sewing machines of anymanufacturer, simply by manufacture of the table top 14 with a pluralityof inserts being also manufactured each of which is adapted to support adifferent make, model, or size of sewing machines. The structure isparticularly useful in businesses in which, for example, there is alarge operation in respect to the conversion or renewing of sewingmachines, and the sale of traded-in equipment. In such an establishment,merely by manufacture of a single type of table and a plurality ofinserts for receiving different machines, any machine can be mountedattractively upon a table, and when so mounted, will appear to have beendesigned particularly for installation on said table or cabinet.

While I have illustrated and described the preferred embodiments of myinvention, it is to be understood that I do not limit myself to theprecise constructions herein disclosed and the right is reserved to allchanges and modifications coming within the scope of the invention asdefined in the appended claim.

Having thus described my invention, what I claim as new, Yand desire tosecure by United States Letters Patent is:

ln the combination of a power-table having atable top provided with arectangular cutout therein opening outwardly of one side of theV tabletop and with openings adjacent the front and rear corners of the cutoutportion, a sewing machine adapted to be received within said cutout, apower transmitting motor supported by said power-table and meansoperatively to connect said motor with said sewing machine; theimprovement consisting in the provision of a unitary means for mountingsaid sewing machine within said table cutout, said unitary meanscomprising an insert adapted to'be remov- V ably mounted within saidtable cutout, means -for locking said insert to said table top, saidinsert having a rectangular shaped cutout formed therein of a size andshape to accommodate said sewing machine and having openings at thecorners thereof, ledges formed in the insert at the corners of thecutout for removably supporting the sewing machine thereon andcushioning pads on said ledges, said locking means including anelongated at bar extending along the front long edge of the insert onits bottom surface and underlapping the adjacent edges of the table top,said bar having openings in line with the front corner openings of theinsert, and in line with the front corner openings of the table top,bolts extending through said aligned openings, nuts on said bolts, atbar brackets extending diagonally across the rear corners of the inserton the bottom surface thereof, said brackets having openings in linewith the corner openings in the insert and the rear corner openings inthe table top, bolts extending through said latter aligned corneropenings, and nuts on the ends of said bolts.
